MAP with Link?

[Loewen21]

Hey guys just looking into dsm link, im running an hks vpc/gcc setup right now. Wondering if i can run my MAP sensor with dsm link?

 

[2gGSX]

Yup, just wire it up to a 5v input (EGR temp, and/or baro/intake temp depending on if you have a MAFT setup).

 

[Loewen21]

Alright so i could just wire it all into the air intake temp? Including my air intake temp sensor?

 

[2gGSX]

No, it's one input per input--e.g. if you have to wire your wideband into one input, and your MAP sensor into another, and an IAT sensor to another, and so on. Having two signals in one input creates an interference which screws with your reading.

Once you switch to link you will no longer need the VPC temp sensor. It will be measured by any mitsu mass air meter or clamped via the translator if you go that route.

If you stick with a mitsu mass air you can only use the egr temp or front o2 (if run open loop all the time). Go with a gm setup and you get a few more inputs (iat and baro).

Check out this post. This is how turbosax2 (my brother) and I wired up my car. (Obviously your wire numbers and colors will be different than mine - here's your ECU pinout: http://www.dsmlink.com/images/forums/1GECUPinout.pdf). I'm running a wideband and AEM IAT and 5 Bar MAP sensors which are integrated into DSMlink. I'm also running a MAF-T setup so I can use the extra inputs (baro and IAT for a 2g).

Here are the inputs you can use as a 1g:

1G ECU:

* EGR Temp Input (ECU Pin 15)
* IAT Input (ECU Pin 8) -- Only usable when using MAFT with "Ignore IAT/Baro" selected.
* Baro Input (ECU Pin 16) -- Only usable when using MAFT with "Ignore IAT/Baro" selected.
* Front O2 (ECU Pin 4) -- Only usable when "Open Loop" option is selected.
* Park/Neutral switch (ECU Pin 104) -- Available on MT ONLY. Used exclusively for clutch cut input.

I would only put 1 item to each input.

Alright well all i have right now is taht intake temp sensor and MAP sensor. what else do i need to make this work

 

[snowborder714]

You will need to pick which one you want connected for DSMlink. Also, which sensors do you have?

 

[turboglenn]

Both link systems i've tuned on DSM's had a GM 3 bar map sensor for load sensing. So yes you can.. How to set it up *shrugs* you might want to contact the manufacturer on that. I'd have to call the only people i know runing link and see if they have the manual. One of the local shops who put them in a few cars around here, usually keeps the manual so you can't do anything on your own. And probably so you can't find that he put 40+ degrees of timing in one RPM range in high boost... All of that so you become a "repeat customer"
oooops.. i forgot to hit "reply" about an hour ago

 

[Loewen21]

As for what sensors, i have a GM 3 Bar and the intake temp sensor im not too sure

 

[2gGSX]

Do you have a MAFT setup? If not, then the only commonly used input that you have available is the EGR Temp Input. You will have to cut the 5v output wire from the EGR Temp sensor, then splice in the output of whichever ONE (1) sensor you choose to use into the tail of the wire leading to the ECU.

After that, start logging the sensor you chose in DSMLink, and select EGR Temp when prompted for the input data.

 

[Loewen21]

I haven't really heard too much about it maybe i'll have to do some research and look into it. So i can run link with just a gm 3 bar and it will work fine for me?

 

[2gGSX]

AFAIK link STILL needs a MAF sensor, the MAP is for MAF overrun. Anyone correct me if im wrong.

Yes, for now.

 

[2gGSX]

If you've ever looked at any of the ECU's code or DSMLink's code, you'd understand just how hard it actually is. No one seems to be having problems with using V2, although it is human nature to always want more.

Do we need speed density? No, but it'd be cool.
Do we need integrated MAF support? No, especially not with speed density, but it'd be cool.
Do we need an ECU-based boost control system? You get the idea.

I'm going to have to take a closer look at my friends 99 GSX with DSMLINK and see how he's running on MAP alone. I tuned it after the shop who installed it blew his motor tuning it and he got a new engine in it and didn't want them touching it. Everything was based on a 3 bar MAP and tuning it was a breeze. *scratches head* Hmmm?

Alright, well that would be great if i could just run it on that, don't wanna have to throw a MAF back in there after its all been removed might just have to go big and go with an AEM then. But ya if you could figure out how he got that to work for him that would be great.

 

[2gGSX]

do you even know who I am ?

After following the link in your profile to your home page, yes.

I'm just stating my opinion. I'm sure you know that there are inherent drawbacks to running a speed density setup as well, mainly the fact that you need to map out your VE every time you change anything, and the risks of a sudden change in VE.

glenn/OP--you could enable FakeMAS at a very low RPM and run the car in that mode constantly, which in theory would allow you to run only a MAP sensor and get rid of the MAS completely. This probably isn't the best of ideas though, and I wouldn't recommend it.

I'm supposed to see him tonight after work... I'll let you know what i find out.

EDIT: nevermind, he's running "link" not DSMlink... i thought it was the DSm one , but i guess not.

Haltech for the win!!!! AEM's are just over popularized by excessive magazine adds and TV spot highlights. The amount of variables and things that might not get setup right by a first tiem user on an AEM EMS ( non plug-n-play ) would drive a normal guy to hang himself :

Don't get me wrong, I like the AEM a lot, but for user friendly-ness and range of flexiblity without having to consult AEM to change the function of a simple output makes me a much bigger fan of systems like haltech, motec, autronic and so forth that are soley designed as "universal" instead of just having one model that's not plug-n-play. I use to have nightmares about teh first 5 AEM units i had at my shop. (just after the PEFIS switch to AEM time erra ) And i even had direct support through the guy who sold it to AEM when it was the PEFIS system, but at least teh newer software is a bit friendlier

Did you read what the OP even said, they want to run link in speed density anyways.

I haven't even dissed on link except for the million year wait, everyone is waiting on for v3. However you seem really butt hurt about it. Just forget it.

Loe if you want real speed density, get AEM, megasquirt, or get dsmap. Two of them have pain staking enrichment maps to mess with, one doesn't.

Honestly, no one's writing anything in a threatening manner other than you. It's great you developed and are giving people another option to go with, but you almost seem threatened when people bring up any other system in discussion. Step back from the keyboard and calm down? I won't bother you with any more responses about this, sorry for wasting your time.

OP--Glenn and hakcenter are both giving good advice if you are really set on running the car in SD. All the standalone systems will have the greatest capabilities, but as stated above, be that much harder to tune. You could try asking people local to you who have standalone systems and see what they feel about it, as it's a much different from using anything that retains the stock ECU.

Alright, well right now i think im gonna start saving and stick with my vpc set up for a bit. Then convert over to AEM. There's a bunch of DSM guys i know around this area running it (4 or 5) who i'm sure will be willing to help me set it up, so i shouldn't be too bad off there.

Yeah, help is really easy to find for the AEM.

That is, until you really need it.

 

[turboglenn]

The F.A.S.T. is good too from what i've heard. I've never played with one but, it seems to be a decent system. The first ones were almost a clone of the newer ACCELL DFI gen7 ( at least when i looked over the software) But the newer one's look quite a bit different, might be time to research it a little tonight! I wonder if it's now supporting waste spark? The first one's didn't

Good call!

What about the maftpro unit? Really good solution for a 1g, controls timing (w/dsmchips eprom which will also kind of cover knock via the stock boost gauge), boost control, wideband tracking, data logs, and a whole bunch more I dont remember. Will work really well with his existing sensors as well. I almost ran it until I found out i couldnt do anything about timing on a 2g. It has some real benefits that dsmlink doesnt have. Although, there are the dsm link forums which are definitely a huge plus.
